Lette/rs Patent No. 84,047, dated November 17, 1868.

To all whom t may concern:

Be it known that we, J. H. BoDrNrr and T. A. HrLL, of Mount Morris, inthe county of Livingston, and State of New York, have invented anervandimproved Water- Wheel; and we do hereby declare that the following is afrrll, clear, and exact description of the construction and operation ofthe same, reference being had to the accompanying drawings, making apart of .this specification, in which- Figure 1 is a vertical axialsection of wheel and curb.

Figure 2 is a bottom view of the gate.

. In this inventionthe gate is made in a peculiar form, to adapt it tobe opened and closed with less power, and a novel device is employed forthe purpose of moving it; Iii-addition to this, the curb is soconstructed that as the step wears away, the joint between the wheel andthe curb still remains water-tight In the drawings, A represents thecurb, having tight side walls, arid so constructed that. the waterpasses vertically to the wheel;` B, the wheel, of the verticaldischargepattern; C, the shaft;. F, the central cone, surrounding the shaft abovethe wheel; D, the step; and E E, braces, by which the step and itssocket,'sup ports, and adjusting-apparatus are attached to the curb.

The curb is provided with an elongated rim or flange, a, around itslower edge, which encircles the upper part of the wheel B, the jointbetween them being watertight.

This iiange extends down over' the sides of the wheel so far that if thestep D should wea'r away and drop the wheel down a considerabledistance, it would not affect its action, inasmuch the flange wouldstill cover its upper edge, and prevent the escape of the water aroundit.

The curb is covered by a ilat circular plate, provided with suitableapertures around its outer edge, orrtside of the cone F, to admit theproper supply of water through the chutes H H to the wheel.

I is the gate, in the form of an annular plate, lying flat upon thecover of the curb, and encircling the cone F, being provided with aseries of openings, 'i i, at suitable distances apart, to open enclose'the chutes H H to any requireddegree, as the gate is rotated in one4direction or'tlrc other. 4

The openings i lare usually oi' thc same size and dimensions as thesolid parts i i', between them.

The solid parts ol' are made concave on their under side, as see'n Aat cc, iig. l, and shown by fig. 2, so that the only parts o f the gatewhich bear upon the surface of the curb are the rings in n, at itsedges, and the bars o o, which connect them.

The gate, thus constructed and operating, is opened and closed by thefollowing apparatus:

A bevel-gear wheel, w, on au upright spindle, S, pro- The Schedulereferred to in those Letters Patent and making part of the lame.

vided with a harrd-wheel, s, serves to operate a. horizontalscrew-shaft, T. A block, R, screws back and forth along the lattershaft, 'as the hand-wheel above, is turned, and, as it vscrewsback andforth, moves the gatearound by means o'f an arrn,'v, which is hinged orjointed to the gate at one end, and the blockat the other.

This device not only operates withl great power, but

'holds the gate so rm'ly in anyrequired. position, that it cannot bemoved,'except from above, by turning the s indie.

pP P represent the frame, attached to the curb, which vsupports thescrew-shaft and spindle.

'lhe gate, thus constructed and operated, is one of the most firmand-durable ever invented, while it can bc opened and closed moreeasilykthan any other heretofore brought into use.

Having thus described our invention, we do not claim a water-wheelr withside-feed and centre-vent, working in connection with flanges upon acurb having side gates and a tight cover, said flanges being for thepurpose of directing the entire volume of water to the centre of thewheel; neither do we claim a combination ofhand-wheel, shaft, andworm-screw, for the purpose of working the gate. The flanges a a, uponour curb, are intended to be used only in connection with a wheel havingthe-top feed, its sides being cylindrical, and the side walls of thecurb being watertight; and the arrangement for operating the gate islimited to the particular combination of cog-gear, screw-shaft, andarrn, described and shown.

What we do claim as our invention, and desire to secure by LettersPatent, is-

l. The arrangement ofthe top-feed vertical-discharge wheel B, inconnection with the ilangesa a, upon'the lower edge of a curb, which has.the gate at itstop, its side walls being water-tight, substantially asand for the purpose herein set forth.

2. The gate I, when cast with recesses or concaves, c e, on its undersurface, substantially as specified.

3. The arrangement of wheel B, gate I, arm c, screwshaft fl, block R,working upon the screw-shaft, and spindle S, operating' the screw-shaftby means of coggearing W, when said parts are constructed to operate inconnection with each other in the manner and for the purposes abovedescribed.
